Standard Sizes of Doors & Windows for Residential Buildings in Indian Conditions

Sharing the information Team BricksnMortar provided to one of our followers (Abha Dewan) on twitter based on query received from her via our twitter handle #bricksnmortar

Query : What are the various standard sizes of doors and windows that one can choose from in Indian conditions?

Team BricksnMortar's reply :
Dear Abha, foremost there is hardly anything in this world today which can't be adopted as a desirable size in terms of doors and windows. Architectural features and sizing requirements have been changing from time to time. Just think, how big sized doors and windows the historic forts and palaces used to have? They used to be huge!

Coming back to the point, we presume you are asking about the conventional standards for door and window design in terms of sizing them for homes, isn't it?

As for Indian conditions, the best reference would be the government publications and design manuals that provide guidance for sizing them as well. We are sharing herewith the guidelines inferred from the Government of India incorporated Central Public Works Department's (CPWD) manual, titled: 'Manual for Doors and Windows details for Residential Buildings', which mentions:
